8220 THRU 8233 PRELIMINARY INFORMATION (subject to change without notice) January 18, 2000 LOW-DROPOUT REGULATORS — HIGH EFFICIENCY Designed specifically to meet the requirement for extended operation of battery-powered equipment such as cordless and cellular telephones, the A8220SLH thru A8233SLH voltage regulators offer the reduced dropout voltage and quiescent current essential for maximum battery life. Applicable also to palmtop computers and personal data assistants, these devices deliver a regulated output at up to 100 mA (transient), which is limited only by package power dissipation. Regulated output voltages of 2.6, 2.7, 2.8, 2.9, 3.0 and 3.3 are currently provided. Other voltages, down to 2.0 volts, are available on special order.
